DESCRIPTION  
The DS1602 is a real-time clock/elapsed time counter designed to count seconds when V power is  
CC  
applied and continually count seconds under battery backup power with an additional counter regardless  
of the condition of VCC. The continuous counter can be used to derive time of day, week, month, and year  
by using a software algorithm. The V powered counter will automatically record the amount of time  
CC  
that V power is applied. This function is particularly useful in determining the operational time of  
CC  
equipment in which the DS1602 is used. Alternatively, this counter can also be used under software  
control to record real-time events. Communication to and from the DS1602 takes place via a 3-wire serial  
port. A 1-byte protocol selects read/ write functions, counter clear functions and oscillator trim. A low  
cost 32.768kHz crystal attaches directly to the X1 and X2 pins. If battery powered-only operation is  
desired, the VBAT pin must be grounded and the VCC pin must be connected to the battery.  
Note:Some revisions of this device may incorporate deviations from published specifications known as errata. Multiple revisions of any device  
may be simultaneously available through various sales channels. For information about device errata, click here: www.maxim-ic.com/errata.
